Parse Server before 8.6.106 and 9.0.0 before 9.10.5-alpha.7 afterSave Trigger and LiveQuery Bypass via Dot Notation Keys

Parse Server before 8.6.106 and 9.0.0 before 9.10.5-alpha.7 mishandles dot notation keys with null or undefined values when building the saved object, so a write is stored but returns an error and skips afterSave triggers and LiveQuery events. A client with write access can exploit this to evade audit logging, notifications, and derived data updates.
